DESCRIPTION
The TPS4000x are controllers for low-voltage,
non-isolated synchronous buck regulators. These
controllers drive an N-channel MOSFET for the
primary buck switch, and an N-channel MOSFET
for the synchronous rectifier switch, thereby
achieving very high-efficiency power conversion. In
addition, the device controls the delays from main
switch off to rectifier turn-on and from rectifier
turn-off to main switch turn-on in such a way as to
minimize diode losses (both conduction and
recovery) in the synchronous rectifier with TI’s
proprietary Predictive Gate Drivet technology. The
reduction in these losses is significant and increases
efficiency. For a given converter power level, smaller
FETs can be used, or heat sinking can be reduced
or even eliminated.

DESCRIPTION (continued)
The current-limit threshold is adjustable with a single resistor connected to the device. The TPS4000x
controllers implement a closed-loop soft start function. Startup ramp time is set by a single external capacitor
connected to the SS/SD pin. The SS/SD pin is also used for shutdown.
